Sustainable Drinking Water Security Strategic Plan: A Case Study of Juba South Sudan

Abstract

South Sudan is currently fronting significant difficulties to achieve the 2030 Sustainable Development Goals 6 (SDGs) framed in 2015, concentrating on water as a path to sustainable development. The country capital city Juba is one of the drinking water insecure towns in the world due to a long civil war that destroyed basic infrastructures, encourage urbanization and rural urban immigration. This paper aimed to investigate drinking water quota per capita per day in other countries, suggest a drinking water budget per capita per day to Juba, estimate optimum capacity for drinking water treatment plant to the city, and recommend a suitable drinking water distribution system. Literature review methods under meta-analysis were conducted to assess the drinking water budget per capita per day for cities in the world and to investigate advantages and disadvantages of some drinking water distribution systems. Mathematical models were used to estimate the capacity of the drinking water treatment plant required in the city. The study concluded that amount of water needed for the city is 36 x 103 m3. It should be 35 x 103 m3 for the western side and 12 x 102 m3 for the eastern side of the city. It also found that a looped drinking water distribution system is the best option for the city. The study suggested construction of a new drinking water treatment plant to secure drinking water security and improve the drinking water distribution network.
